Abstract
Abstract A rectifying power supply having circuitry for providing AC power, a plurality of capacitors responsive to the AC power for providing DC isolation and for providing capacitively coupled AC power, and a plurality of rectifying circuits responsive to the capacitively coupled AC power for providing respective DC outputs. The outputs of the rectifying circuits are coupled in series or in parallel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
56 words
A power supply comprising: means for providing AC power at a frequency greater than one megahertz; non-resonant means responsive to said AC power for providing DC isolation and for providing capacitively coupled AC power without inductors or resistors; and a plurality of rectifying means responsive to said capacitively coupled Ac power for providing respective DC outputs.
Claim 2
Dependent Claim
56 words
A power supply comprising: means for providing AC power at a frequency greater than one megahertz; non-resonant means responsive to said AC power for providing DC isolation and for providing capacitively coupled AC power without inductors or resistors; and a plurality of rectifying means responsive to said capacitively coupled Ac power for providing respective DC outputs.
Claim 3
Dependent Claim
33 words
